文摘
- •
Parameters assessing mixing intensity are developed.
- •
Experimental temperatures are Hilbert–Huang transformed where mixing is strongest.
- •
Relevant temperature frequencies from 0.03 to 0.10 Hz where mixing is strongest.
- •
Main spectral peaks imputable to intrinsic mode functions reflecting the largest time scales.
- •
The relationship between temperature and velocity spectra is analyzed with CFD.
